Hi Everyone,
I am restoring a 4/4 cvh and need to replace the brake master cylinder. When I removed the old one I found the actuating push rod was bent!
Do 4/4s need that much pedal pressure?
I see Heart of England Morgans's sell an adaptor to fit the later type master cylinder that has a servo.
Has anyone fitted one?
Thanks,
philb

Shouldn't do Phil - unless the brakes have not been looked after (people seem to forget how to look after drum brakes nowadays). I can lock all four wheels on RTA reasonably easily (no servo).

'Fraid I have no experience of the HoE servo kit.

Looking forward to seeing the car one day! thumbs

Cheers,

I fitted the Mulfab 4 pot caliper upgrade to a 1981 4/4. It turned out that the new calipers were in conflict with the damper blades, so I had to do the roller bearing conversion as well.

End result: Much better brakes with much less pedal pressure and lighter steering. No need for servo!

How much lighter does the roller bearing conversion make the steering?
And do you think it's worth doing that conversion on it's own, or does it make more sense to do it when the kingpins are ready?

I'm thinking about the next modification........and am due to visit Mulfab quite soon. thinking

On the 4/4 the steering effort never was a problem. I was forced to do the conversion to make room for the bigger calipers. After the steering bearing conversion, the steering almost became too light. I never liked the cam and peg steering and when I traded in the 4/4 for a brand new +4 in 2008, the rack and pinion steering was the greatest improvement apart from the 2.0 Duratec compared to a 1.6 Kent.

Your roadster should have roller bearings as standard. Otherwise,
if you go for the steering bearing conversion, it is best to wait and do it when you replace kingpins. You will also have to change to shorter main springs to allow for the bearings.

It'a an early(2005) Roadster Harald, so it has damper blades, but post 2006/7 stub axles - (the story as to why was related on TalkMorgan in one of my earlier posts).
I'll see what they think at Mulfab as Peter uses a 2005 Roadster as a 'test bed'. I realise the springs are shorter, and there's also a choice of spring spec.
I might also look at the rear axle offset plates while I'm there.

Dave,
Talk to Peter Ballard about spring rates etc. Alternatively see if Uncle Melvyn still has a copy of The Morgan World with Peter's article.
Very interesting reading.

Scroll down to "Offset Blocks".
It's a foible of the Series 1 Roadster, and I fancy an afternoon grappling with leaf springs.

Hi DaveW
thank you for the info, I remember mentioning that I wondered why Morgan did not centre the rear wheels in the arch.
Now I know the solution crazy2
When I bought my Morgan, little did I know what an adventure it was going to be.
Every time I come on here I learn something new and interesting.
Almost anything can be modified and altered, improved to the tenth degree.
All I can do with my everyday Landie is grease the prop-shaft, change all the oils and filters, wash and polish, all so mundane yawn
The list of improvements for a classic Morgan are seemly endless, and that's how I now like it.
Every drive is a challenge,
will I arrive in one piece,
will the shimmy shimmy take me by surprise,
are the tyres to hard,
lastly will my hat blow off and cause a massive pile up on the F4 free-way? happy3
Peter
